Related to #4186.
Some notable changes:
- The term 'Error' now strictly refers to native Error objects defined in
the ECMA standard, which are ordinary objects. All other uses of
'error' or 'error reference' where the term refers to a thrown value is
now called 'exception'.
- Simplified the naming scheme of many String API functions. These functions
will now also take an 'encoding' argument to specify the desired
encoding in which to operate.
- Removed the substring-copy-to-buffer functions. These functions
behaved awkwardly, as they use character index to specify the
start/end positions, and were mostly used incorrectly with byte
offsets instead. The functionality can still be replicated with
other functions if necessary.
- String-to-buffer functions will no longer fail if the buffer is not
sufficiently large, the string will instead be cropped.
- Fixed the usage of the '_sz' prefix in many API functions. The term
'sz' means zero-terminated string in hungarian notation, this was
used incorrectly in many cases.
- Renamed most of the public API functions to have shorter, more on-point
names, rather than the often too long descriptive names. Functions are now
also grouped by the type of value they operate on, where this makes
sense.

Instead of a fixed number of arguments, a call info structure is passed
to the handlers, which can be extended in the future without breaknig the
API. This structure holds new.target value, so its getter function is removed.

This patch disables automatic detection of module code, and instead
requires the user to explicitly specify whether to parse a source
as a module or as a script.
To achieve this the jerry_parse API function now takes a new option
which signals that the source should be parsed as a module.

- Type for realm objects is introduced (ecma_global_object_t)
- Realm reference is added to built-in objects and ECMAScript functions
- Resolving built-ins, global environments, and scopes require realm object
- Unnecessary global object accesses are removed from the code
Missing: external functions and static snapshot functions have no realm reference

The old variant of the syntax error printing method could incorrectly
over-read the source file contents.
JerryScript-DCO-1.0-Signed-off-by: Peter Gal pgal.usz@partner.samsung.com
The minimal variant became quite meaningless lately. There were two
port APIs originally that had extra functions in the default port
in addition to the core-mandated implementations: the I/O and
Termination port APIs. However, the extra Termination API code was
removed a year ago, leaving some minimal extension in the I/O port
only. As the overhead of the extension is negligible, it is not
worth maintaining two library variants.
Therefore
- this commit removes the minimal variant of the default port lib,
- rewrites uses of the minimal variant to use the variant with the
I/O extension, and
- updates targets where I/O port code was copy-n-pasted.

This change introduces simple stack measuring by coloring the stack
before doing the actual JS work.
The dynamic linking should be avoided as it will use the stack during
the symbol resolving.
At this moment the `JERRY_STACK_MEASURE` compile time define will enable
the measurement for the jerry-test binary.
A usable build configuration:
```
./tools/build.py --jerry-cmdline-test=on --compile-flag=-DJERRY_STACK_MEASURE=1 --compile-flag=-static

Overflows in conversions from floating-point to integer are
undefined behavior in the C99 standard. (Clause 6.3.1.4: "If the
value of the integral part cannot be represented by the integer
type, the behavior is undefined.")
When UBSAN is enabled, this gets reported at `srand()` calls. (The
random seed is usually initialized using the date port API, which
represents dates as `double`s. But `srand` takes an `unsigned int`.
A simple cast from `double` to `unsigned` becomes undefined
behavior if the value is too large. And "now" is too large
nowadays. So, effectively, all executions start with an undefined
behavior.)
This patch fixes this by casting the floating-point value of the
date to an integer through a union.

This change fixes the handling of lexical blocks when executing multiple
scripts, and also fixes a few issues with module environments.
After this change, all script files will run in the same context and
will have access to lexically scoped global variables of previous
scripts, and module environments will no longer have a bound global
'this' value.
The REPL implementation in main-unix is also fixed to correctly handle
lexically scoped variables.
Fixes#3561.

When reading from the stdin a '\n' character or an empty line/file
was expected to end the read. However, in case of an input which is not terminated
with a newline a buffer overflow will occur.
Test case:

```

The -f and --generate-function-snapshot switch are added to the jerry-snapshot
command line tool so the entire javascript input can be interpeted and
loaded as a function snapshot. The function arguments must be given in
the command line.
Example:
echo "return a + b;" > myfunc.js
./jerry-snapshot generate -f "a, b" myfunc.js

The current module implementation resolves module paths relative to the
current working directory, but paths should be resolved relative to the
currently evaluated module/source.
This requires a change in the jerry_port_normalize_path port API
function, so that it also takes the current module path as an argument.
On the engine side, we now also create a module object for the main
script, so that we can properly identify the base path for other
modules.

When using ES6 modules it was not possible to identify which module
an error originates from.
This PR changes the error message to also include the file path using
the file:line:column format, and updates the source context printing for
unhandled exceptions to use the correct file.

- Allow command line tools to build together with libfuzzer driver.
Compile everything with `-fsanitize=fuzzer-no-link` to prevent
linking in libfuzzers's `main` symbol in all executables (causing
duplicate symbol errors in command line tools), and add
`-fsanitize=fuzzer` to the libfuzzer driver only.
- Make ASan optional when building with libfuzzer to allow the user
to choose freely from available sanitizers (e.g., UBSan, MSan,
HWASan).
- Stabilize libfuzzer by resetting PRNG seed at every invocation.

Removed 'jerry_parse_and_save_literals' and introduced
'jerry_get_literals_from_snapshot' instead which works
on snapshot buffers rather than source code. Added literal
saving feature to snapshot merge in the snapshot command
line tool. Also added missing 'jerry_cleanup()' calls to the
snapshot tool. Improved the console messages of the snapshot
tool.
